Preparation of Mesoporous Hydroxylapatite Ceramics Using Polystyrene Microspheres as Template

Article Preview

Abstract:

Mesoporous hydroxylapatite was prepared by Liquid phase precipitation method, using Polystyrene microspheres as template. Polystyrene microspheres mixed uniformly with the prepared hydroxylapatite slurry, then the mixture dryed and sintered at reasonable temperature, mesoporous hydroxylpatite ceramics were obtained. The phase constituent was analyzed by X-ray diffraction (XRD) and the microstructure was observed under scanning electron microscopy (SEM). The results showed that the prepared mesoporous hydroxylapatite ceramics were of high purity and their pores were evenly distributed, with big pore 0.8-1.0 um and small pore 30-80nm in diameter.
